OLASSIlflCATION OF THE ASCALAPUIDJE. 255 



Pedes flavi, femoribus (ad apicem exceptis) tarsisque fusco-nigris. 

 Abdomen nigrum, supra linea mediana, lateribus, infra margini- 

 busque posterioribus segmentorum, flavis. Alas subfequales ; hu- 

 meris, area subcostali, pterostigmateque, flavis; cellulis are^ post- 

 stigmaticalis triseriatis. Long. corp. 13-14'"; exp. alar, antic 29- 

 35'", postic. 24-29'". 

 Probably distributed throughout New Holland. 



2. S. IMPORTUNA, Walker. (Aseal. importunus, Walk. Cat. Brit. 

 Mus. Neurop. p. 427.) S. flavipedi valde affinis, sed pauUo minor ; 

 alis angustioribus, pallide fuliginoso-tinetis. 



Hab. Morcton Bay. 



Evidently very closely allied to aS^. Jlavipes, but apparently 

 distinct, in consequence of the narrovsr and tinted wings. I have 

 seen two individuals precisely similar. 



3. S. suBTRAHENS, Walker. (Ascal. subtrahens, Walk. Cat. Brit. 

 Mus. Neurop. p. 430.) Antenna; tenuiores, nigra;, ad basin flava; ; 

 clava flava, infra dimidio apicali uigro. Frons pallide flavus, in 

 medio nigricans, cano-villosus. Vertex nigro-villosus. Occiput fla- 

 vum, nigro-radiatum. Thorax supra murinus, utrinque niger; infra 

 vel pruinoso-albidus, vel utrinque linea flavida signatus. Pedes nigri ; 

 posticis ad femorum apices, interraediis femoribus omnino, anticisque 

 (tarsis exceptis), flavis. Abdomen nigrum, supra vitta dorsali inter- 

 terrupta, aurantiaca, ornatum. Alae elongatae, suba;quales ; humeris 

 flavidis; pterostigmate in anticis pallida brunneo, nigro-venato, in 

 posticis nigro, vel nigro-fusco ; area subcostali vix brunneo-tincta ; 

 cellulis areae poststigmaticalis irregulariter triseriatis ; in serie infe- 

 riore magnis, ceteris parvis. Long. corp. 14'" ; exp. alar, antic. 32'" j 

 postic. 28'". 



Hab. Australia. I have seen specimens from Rockhampton and from 



South Australia. 

 One example in my collection has the apical quarter of the 

 posterior wings faintly tinged with brownish. 



4. S. WiLSONi, nov. sp. Caput, thorax, pedes alseque fere ut in C. 

 flavipede (antenna; mutilatae); venulse transversa costales, et infra 

 radium, fusco-marginatae. Abdomen nigrum, macuhs dorsalibus mar- 

 ginibus segmentorum (supra interruptis), infraque ad basin et ad 

 apicem, flavo-ornatum ; apex pilis brevibus nigris utrinque vestitua. 

 Long. corp. 14'"; exp. alar, antic. 32'", postic. 27'". 

 Hab. South Australia {C. A. Wilson). In my collection. 

 The wings are rather narrower than in Jlavipes, and the fuscous 

 margining or clouding of the costal and radial nervules gives 

 them a different appearance. The dorsal margin of each abdo- 

 minal segment appears to have a tendency to expand.
